By inspection, the only two numbers between 40 and 50 that have a GCF of 7 are 42 and 49.
Another way to work out this problem is to list the multiples of 7. They are:
7, 14, 21, 28, 35, 42, 49, 56, ...
The values between 40 and 50 are 42 and 49.

No, 36 and 38 are two numbers between 30 and 40, Their GCF is 2.
Let the two numbers be x and y. Let suppose that the average of two numbers is 20. Then,x + y = 40 and 40/GCF = 5, where GCF = 40/5 = 8Since LCM is 48 and GCF is 8, the numbers are 16 and 24, whose average is 20 is true.
The GCF is 8.
You need at least two numbers to find a GCF. If that's 44 and 40, the GCF is 4.
4 and 40 8 and 20
